A high sell-through means you ordered the right amount; a low one means excess stock that may need markdowns. Fashion retailers often aim for 60–80% over a season; grocery items need much higher rates because they spoil.
How to use the Sell-Through Rate Calculator
- Units received (or beginning inventory)
- Units sold
Results update as you type, and every field accepts the units shown in its menu.
How it works
Enter the number of units received (beginning inventory plus deliveries) and the units sold in the period.
Inputs explained
| Field | What to enter |
|---|---|
| Units received (or beginning inventory) | A number |
| Units sold | A number |
What each result means
- Sell-through rate = [Units sold]÷[Units received (or beginning inventory)]×100
- Units left = [Units received (or beginning inventory)] – [Units sold]
Example values
How the main result changes when Units received changes and everything else stays at the example values above:
| Units received (or beginning inventory) | Sell-through rate (%) |
|---|---|
| 600 | 130 |
| 900 | 86.67 |
| 1,200 | 65 |
| 1,500 | 52 |
| 1,800 | 43.33 |
| 2,400 | 32.5 |
Formula
Sell-through rate = units sold ÷ units received × 100
Worked example
Inputs: Units received (or beginning inventory): 1,200; Units sold: 780.
Results: Sell-through rate = 65 %; Units left = 420; Rating = Healthy.
